Embodiment
As shown in Fig. 1～5, the present embodiment is the connection structure that hypomere precast concrete tower cylinder 1 is connected with upper section steel tower tube 4, and this connection structure forms primarily of end steel plate 15, joint bolt 2, concrete leveling layer 3 between concrete towers cylinder 1 and steel tower tube 4.
Precast concrete tower cylinder 1 top is provided with end steel plate 15, whole loads that this end steel plate passes for undertaking top steel tower tube 4. The prestress wire 11 of end steel plate 15 through being embedded in advance in concrete towers cylinder 1 is fixed on concrete towers cylinder 1 end face, above this end steel plate, perfusion forms concrete leveling layer 3, installing steel tower tube 4 on concrete leveling layer 3, end steel plate 15 is connected by the joint bolt 2 being embedded in advance in concrete leveling layer 3 with steel tower tube 4.
This example middle-end steel plate 15 is as the anchor slab of prestress wire 11, simultaneously also as the lower flange of joint bolt 2, this end steel plate 15 evenly has some bolts hole 18, steel strand perforation 16 and concrete placement hole 17, prestress wire perforation 16 is for through prestress wire 11, the size in concrete placement hole 17 is generally 100～200mm, for blanking during casting concrete with vibrate. Prestress wire 11 in precast concrete tower cylinder 1, prestress wire 11 arranged outside has sleeve pipe 12, arranges the anchoring device 13 of prestress wire 11 on end steel plate 15, prestress wire 11 anchoring on end steel plate 15.
